PERFORMANCE
The container spreader is a key device used to lift containers. Its main function is to lift from the four corner fittings on the top of the container. The structure of the spreader usually includes a metal structure frame, a twist lock device, a guide claw device, etc. According to different needs, spreaders are divided into many types, such as fixed spreaders, telescopic spreaders and rotating spreaders. Fixed spreaders are mainly for containers of specific sizes, while telescopic spreaders can adapt to containers of different sizes by adjusting the length, such as 20-foot, 40-foot and 45-foot containers. In addition, the rotating spreader can rotate the container during the lifting process, making it easier to place it in a specific direction or in a small space.
The working principle of container spreader mainly relies on its internal mechanical or hydraulic mechanism. For example, the telescopic spreader realizes the telescopic action through the reduction motor drive chain transmission. When the telescopic beam reaches the specified position, the limit switch cuts off the power supply to stop the movement. The rotating spreader completes the rotation by driving the pinion of the reduction motor to drive the slewing bearing. These designs not only improve the flexibility and adaptability of the spreader, but also enhance its operation ability in complex environments.
APPLICATION
Container spreaders are widely used in various fields of modern logistics and cargo handling, mainly including port terminals, railway freight, logistics warehousing, ship transportation, manufacturing and special industries. At port terminals, spreaders cooperate with quay cranes, yard cranes and other equipment to achieve efficient container loading and unloading between ships and yards; in railway freight, they are used for rapid transfer between trains and trucks to improve multimodal transport efficiency; in the logistics warehousing field, automated spreaders are used to optimize container storage and sorting; in ship transportation, corrosion-resistant spreaders are needed to adapt to the marine environment.
